Shortly after getting the Ryan Fitzpatrick deal done Wednesday, Jets general manager Mike Maccagnan allowed himself a few moments to take a deep breath and feel good about getting his quarterback re-signed.

“I think, for about a night, I felt a big sigh of relief, and then it was like, ‘OK, back to work,’ ” Maccagnan said Friday.

It has been a memorable offseason for the second-year GM. He had two high-profile, sometimes-contentious negotiations with Fitzpatrick and defensive star Muhammad Wilkerson. In the end, Maccagnan got both deals done, and coach Todd Bowles has been able to have his complete team in the building for the beginning of training camp.

Overall, you have to give Maccagnan a good grade for his offseason. The Jets brought back Fitzpatrick, locked up Wilkerson long term, added speed on defense with first-round pick Darron Lee and filled the hole left by Chris Ivory at running back with Matt Forte.

Not too shabby.

Along the way, there were plenty of speed bumps. Both the Fitzpatrick and Wilkerson deals came down to the wire. Wilkerson’s five-year, $86 million deal was done just minutes before the deadline for franchise players to get contracts. Fitzpatrick’s one-year, $12 million contract was finalized just before training camp began, which Maccagnan said was the “demarcation point” for the Jets.

There is grumbling in the agent community the Jets are difficult to deal with and Maccagnan’s communication skills need some work. But the bottom line is he and his lead contract negotiator, Jaqueline Davidson, got nearly everything accomplished a Jets fan could have hoped for this offseason outside of bringing back Damon Harrison, which was financially impossible.

Bill Parcells liked to say, “Don’t tell me about the labor pains, just show me the baby.”

For Maccagnan and the Jets, the baby looks pretty good. Now, they have to see how it grows over the next few months.

When Maccagnan took the job 18 months ago, he inherited a terrible roster after John Idzik’s disastrous two-year reign. Maccagnan could have gone into 2015 with some minor upgrades to that roster, focusing on a long-term rebuild. He decided that was not the way to go in New York and signed some big free agents and made the big trade for Brandon Marshall so the Jets could be competitive in the short term while also building for the long term. Every deal done in 2015 except Darrelle Revis’ was done with the idea of maintaining flexibility after the 2016 season, making this is an evaluation year for a chunk of the roster.

This is Year 2 of that process, and looking at the Jets’ roster, you can see a team in the middle of it. The roster is heavy on players 30 years old and over, particularly on offense, and now just trying to work in some of the young players they are counting on in the future.

Maccagnan shied away from making any playoff promises Friday when asked if this team is playoff-caliber.

“We did some things we think will help us be a better team,” he said. “We’ll see how that plays out over time.”

The variable for this team is how age affects it — both old and young. Does the 32-year-old Marshall fall off the cliff this year after breaking franchise records in his first season? Does Forte, now 30, have anything left? Does second-year linebacker Lorenzo Mauldin blossom into an every-down player? Does 24-year-old Calvin Pryor make the leap from good player to Pro Bowler?

No one knows the answers, not even Maccagnan, but he has put the pieces in place for a successful season, capped by the Fitzpatrick deal.

He earned that sigh of relief. Now, it’s time for him to get back to work.
